Meta-search Engine's

Once you choose and save the order of the search engines, you will never have to do it again
Mamma
The mother of all search engines lets you put the top engines to work, even searching for MP3, images, or sound files. Mamma is what is called a smart meta search engine. Mamma will analyze your query and properly format the words for each source it probes. Mamma will then organize the results into a uniform format, and presents them by relevance and source. Mamma makes it easy for you to find what you need. Also note that Mamma is not case-sensitive.
MetaCrawler
Search nine of the most popular engines or Usenet newsgroups. One of MetaCrawler's advantages over other search engines is the standardization of query syntax. Although some people find the use of punctuation a little off-putting, it is really quite straightforward to use, and you can dramatically improve the quality of your results by using these features. When you specify a search, list groups of words that must occur together by surrounding them in quotes. Also, specify words or phrases that must appear in documents by prefixing them with a plus sign, and specify words or phrases that must not appear by prefixing them with a minus sign. There should be no space between a + or - sign and the word to which it applies. There should be a space between individual query terms.
